In the following example \keys_set_groups:nnn ignores every key in
the meta key "default", while \keys_set_filter:nnn "looks" into the
meta key and filters out (as wanted) only the initkey.
When I add the default key to the "init" group the output of
\keys_set_groups:nnn is correct, but now the filter is wrong.
\documentclass{article}
\usepackage{expl3}
\begin{document}
\ExplSyntaxOn
\keys_define:nn {mymodule}
{
initkey .code:n = {init!~},
initkey .groups:n = {init},
laterkey .code:n = {later!~},
laterkey .groups:n = {later},
default .meta:n = {initkey,laterkey},
%default .groups:n = {init},
}
% no output, wanted: init!
\keys_set_groups:nnn {mymodule} {init} {default} \par
% wanted: later!
\keys_set_filter:nnn {mymodule} {init} {default} \par
\ExplSyntaxOff
\end{document}
The only work around I found is to create key copies:
defaultinit .meta:n = {initkey,laterkey},
defaultlater .meta:n = {initkey,laterkey},
but this doesn't look very elegant. Is there a way to assign the
default key to "none and all groups" so that is always processed by
both commands?
